Hey, New to SketchUp
-
Thank you.
-
If you need a little help you can go to the thread above by Curbs for basics such as grouping, jointing and here's the sketchyphysics wiki

Have Fun

Alright, cool. Checking the link right now.

Hi,
at this site you will find very helpfull video tutorials.

Ah, outstanding. Thanks.
Question: I was reading the tutorial that phy told me to look at in the topic, and it talks about debugging to make sure the shape is right. I can't do that; under the right click menu, it goes Debug>Readback Collision Geometry and that's it, no "Run."
-
Yup, that's all we get
It shows you the actual collision geometry of the item, which is what the physics engine 'sees'. It will (sometimes) help fix problems in models.
-
The thing is, it won't show me the geometry that SP "sees." It acts like I didn't do anything =/
-
well you need to play the simulation
-
Play the simulation?... How do I do that?
Sorry if these are dumb questions, this is my first day using SP, lol.
-
Not much point in SP if you don't play the sim! Press the play button
-
To make joints:
-Create two objects
-Create a joint
-Group the joint with one object
-Select the other object with the JCT, then ctrl+click the joint
-Play the sim!
Components are fine. You can also group componets with normal groups. Or normal groups in components. Or whatever...
-
Oh, okay. Sorry.
So I have to hit play before I can view what SP is "seeing" my geometry as?
Also, I'm still not able to use the Joint Connector tool. I kind of assumed all I did was click the icon, then click the joint, and then the "mother" object, but that doesn't seem to be working =/...
EDIT: I got my first successful movement. It was just a ball rolling down a ramp, but I think I'm finally beginning to understand the basics of this program. If I can get the joints to work, I think I can proceed in leaps and bounds.
EDIT2: One more question. I know you need to group everything before using SP. Would a component work just as well? I'm not really sure how all they're different, except that you can make changes to a copy of a group without changing the original. If I, say, made a wheel of a car, and needed to copy it, could I make that a component instead? Or does SP only use groups?
-
I tried that, it's not working =/...
Okay, I'll outline what I'm doing step-by-step, and you tell me where I'm going wrong. I'm sure it's some stupid mistake on my end.
For testing purposes, I'll try to make a wheel on a car, and push it.
- Make rectangle; pull it into box.
- Make circle; pull it into cylinder.
- Make the rectangle a group.
- Make the tire a group.
- Copy tire 3 times.
- Place tire on box (repeat for all tires).
- Place hinge on the center of the tire; use the opposite center as axis (this makes sense in my mind as how to do it, lol). Repeat for all four tires.
- Group tire and hinge together (repeat for all tires).
- Click "Joint Connector."
- Select one hinge, then box (repeat for all tires).
- Place over static ground.
- Hit play.
- Attempt to push.
- Instead of turning, wheels hilariously fall off like it's a Loony Toons cartoon <.< >.>
-
LOL #14 was kinda funny.
It isn't really a stupid mistake. Select joint tool, click on the joint, then holding left control click on the mother object. -
Aha! I got the wheels to turn.
I did a few things differently, and I'm not sure which one fixed it =/...
I put the joint on the inside, between the body and the tire. Before I was putting it on the outside. I also clicked after I ctrl+clicked the mother object. That probably seems like one of the "duh" things, but it never even crossed my mind. I absentmindedly hit enter and went on my way, lol.
But whatever it was, it worked.
I think once I figure out how all the different joints work, I can do some pretty cool stuff with this.
Anyway, thanks a lot for your help, guys. I know noobs like me probably get pretty annoying, lol.
-
Oh something I forgot to tell you was the "UI" button that's on the sketchyphysics toolbar. This button has a window that enables you to modify joints. Wasn't sure whether you knew or not just thought you'd like to know.
-
Yep, that's what I'm playing around with right now.
I'm having some issues getting the controller thing to work.
I've got two blocks with a hinge in the middle, for testing purposes. I name the joint "Main," and then hit play to get my control display up, and I get an error message that says, in a nutshell, "I REFUSE TO COOPERATE MUAHAHA."
I'm sure I'll get it eventually, though.
-
You probably want a controller. It was slightly easier in SP2, but all you need to put is:
slider("name")
-
Ah, thanks. That worked.
